Validation rule

SteamIdRule validates that submitted input resolves to a SteamId. It mirrors the route binding: a 64-bit ID or a /profiles/<id> URL passes, anything else fails. The URL keeps whatever follows the ID — a sub-path, a ? query string, a # fragment — so a link copied straight out of the address bar passes as it stands.

use Fkrzski\LaravelSteamApiSdk\Rules\SteamIdRule;

$request->validate([
    'steam_id' => ['required', SteamIdRule::make()],
]);

use Fkrzski\LaravelSteamApiSdk\Rules\SteamIdRule;
use Illuminate\Foundation\Http\FormRequest;

class LinkSteamAccountRequest extends FormRequest
{
    public function rules(): array
    {
        return [
            'steam_id' => ['required', SteamIdRule::make()],
        ];
    }
}

The rule validates, it does not transform. Build the value object yourself, or let the AsSteamId cast do it on persist:

use Fkrzski\SteamApiSdk\ValueObjects\SteamId;

$steamId = SteamId::tryFromInput($request->string('steam_id')->value());

strict() accepts a raw 64-bit ID only — for an API endpoint documenting an exact format, rather than a field a person types into:

'steam_id' => ['required', SteamIdRule::make()->strict()],

A vanity URL never passes: resolving one needs an API call the rule deliberately does not make. Accepting vanity names? Run Steam::users()->resolveVanityUrl() after validation.

Besides strings the rule takes an int (a JSON body sends the ID as one) and any Stringable, including a SteamId. Surrounding whitespace is trimmed. Every other type — null, arrays, floats, plain objects — fails.

The messages ship as a package translation:

php artisan vendor:publish --tag=steam-api-translations

Published files:

return [
    'steam_id' => 'The :attribute field must be a valid Steam ID or profile URL.',
    'steam_id_strict' => 'The :attribute field must be a valid 64-bit Steam ID.',
];

For a one-off override, pass a message the usual Laravel way instead:

$request->validate(
    ['steam_id' => ['required', SteamIdRule::make()]],
    ['steam_id' => 'Paste your Steam profile link.'],
);
